1 Important safety instructions

Symbols used to mark
instructions

Before using the
high-pressure­cleaner, be sure to
also read the en­closed operating in­structions and keep

them within reach at all times.

For your own safety

The appliance must

• only be used by persons,
who have been instructed
in its correct usage and ex­plicitly commisioned with the
task of operating it.

• only be operated under su­pervision.

• not be used by children.

• not be used by mentally or
physically disabled persons

Warning

• Ensure that any exhaust
emissions are not in the vi­cinity of air intakes.

• This machine shall only be
used with cleaning chemicals
supplied or recommended
by Gerni. The use of other
cleaning chemicals may
adversely affect the safety of
the machine.

• Risk of explosion – Do not
use the cleaner to spray with
flammable liquids.

General

Use of the high-pressure cleaner

is subject to the applicable local
regulations.
Besides the operating instruc­tions and the binding accident
prevention regulations valid in the
country of use, observe recog­nized regulations for safety and
proper use.

Do not use any unsafe work
techniques.

Do not tie the trigger handle
open.

Transport

Transport of the high-pressure
cleaner is easy on its large
wheels.

For safe transport in and on ve­hicles we recommend preventing
the equipment from sliding and
tilting. Secure it with tie-downs
and apply the parking brake on
the castor wheel.

For transport at temperatures
around or below freezing 0°C
(32°F), anti-freeze should be
drawn into the pump beforehand
(see chapter 6).

Before starting the cleaner

If your 3-phase cleaner was sup-

plied without a plug, have it fi tted
with a suitable 3-phase plug with
ground, by a qualifi ed electrician.

Before use, check that the high­pressure cleaner is safe and in
proper condition.

Regularly check whether the
power cord is damaged or shows
signs of ageing.

Use the high-pressure cleaner
only when the power cord is in
a safe condition. (risk of electric
shock using damaged cord!).

Check the rated voltage of the
high-pressure cleaner before
connecting it to the mains power
supply. Ensure that the voltage
shown on the rating plate cor­responds to the voltage of the
power supply.

We strongly recommend that the
power supply to the high pres­sure cleaner be connected via a
residual current circuit breaker.
This device stops the supply of
electricity if the leakage current
to the ground exceeds 30 mA for
30 ms or it has an ground tester
circuit.

Please observe the regulations
and provisions applicable in your

Safety instruc­tions in these op­erating instruc­tions which must

area. Before putting the high­pressure cleaner into service,
carry out a visual check of all the
major components.

CAUTION!
High-pressure water jets can
be dangerous if misused. The
jet must not be directed at
persons, animals, live electri­cal equipment or the cleaner
itself.

Wear appropriate protective
clothing and eye protection.

Do not direct the jet towards
yourself or towards other per­sons in order to clean clothes
or footwear.

During operation of the cleaner,
recoil forces are produced at the
gunvalve and spray lance and,
when the spray lance is held at
an angle, a torque is also cre­ated. The gunvalve and spray
lancemust therefore be held
fi rmly in both hands.

Do not use the cleaner when
other people without protec­tive clothing are in the working
area.

Check that cleaning will not
result in dangerous substances
(e.g. asbestos, oil) being washed
off the object to be cleaned and
harming the environment.

Do not clean delicate parts
made of rubber, fabric, etc. with
the 0° jet. Keep some distance
between high pressure nozzle
and surface in order to prevent
the surface from damage.
Do not use the high-pressure
hose for lifting loads.

NOTE!
The maximum permissible work­ing pressure and temperature
are printed on the high-pressure
hose.

Do not use the cleaner if the
power cord or high-pressure
hose is damaged.

Ensure adequate air circulation.
Do not cover the cleaner or oper-

ate it in inadequately ventilated
rooms!

Store the cleaner where
it will not be exposed to
frost or use antifreeze

liquid!

Never operate the cleaner with­out water. Even brief shortages
of water result in severe damage
to the pump seals.

Water connection

This high pressure
washer is only al­lowed to be con­nected with the

drinking water
mains, when an appropriate
backflow preventer has been
installed, Type BA according
to EN 1717. If the back fl ow
preventer hasn’t been supplied,
one can be purchased from your
dealer. The length of the hose
between the backfl ow preventer
and the high pressure washer
must be at least 12 metres (min
diameter 3/4 inch) to absorb pos­sible pressure peaks. Operation
by suction (for example from
a rainwater vessel) is carried
out without backfl ow preventer.
Contact your dealer for suction
set recommendations.
As soon as water has flown
through the BA valve, this water
is not considered to be drinking
water any more.

Operation

Keep cabinet and service door
closed during operation.

CAUTION!
Unsuitable extension cords
can represent a source of
danger. Always unwind cord
from the reels completely to
prevent the power cord over­heating.

Connectors and couplings of
extension cords must be water­tight.

Extension cords are not recom­mended, however if necessaray
refer to the following recommen­dations:

Cable length
m

Cross section

< 16 A > 25 A

up to 20 m

ø1.5mm² ø2.5mm²

20 to 50 m

ø2.5mm² ø4.0mm²

Do not damage the power cord
(e.g. by driving over it, pulling or
crushing it).

Disconnect the power cord by
grasping the plug only (do not pull
or tug the power cord).

CAUTION!

Unsuitable fuels (e.g. gasoline)
must not be used as they can
explode and catch fi re.

Use clean fuel only, free of mois­ture and contamination. Contact
your dealer for fuel source and
type recommendations.

If the machine is to be operated at
fuel stations or in other potentially
hazardous areas, the machine
may only be employed outside
the hazard areas defi ned in the
German „Technical Guidelines
for Infl ammable Fluids“ applica­ble at the point of use due to the
potential explosion hazard posed
by the burner.

If the machine is to be operated
indoors, the local building regu­lations must be observed for the
discharge of the exhaust fumes
into the atmosphere. Ensure an
adequate supply of fresh air.

If the machine is to be connected
to a fl ue gas stack, then local
building regulations must be ob­served. We will be glad to provide
tips for connection systems, on
request.

CAUTION!

Beware of hot water and
steam discharge up to
150

0

C when operating in

steam stage.

CAUTION!

Do not touch or cover the
exhaust. Risk of burns
and fi re.

hose or cord over the chimney.
Danger for persons, risk of
overheating and fi re.

Electrical equipment

CAUTION!
Never spray electrical equip­ment with water: risk of elect­trical shock and short-circuit.

The cleaner may only be con­nected to a correctly installed
plug socket.

Switching on the cleaner may
cause voltage fl uctuations.
Voltage fl uctuations should not
occur if the impedance at the
transfer point is less than 0.15
If in doubt ask your local electric­ity supplier.

Maintenance and repair

CAUTION!
The cleaner must be discon­nected from its power source
during cleaning of the machi­ne, maintenance, when repla­cing parts or converting the
machine to another function.

Carry out only the maintenance
operations described in the
operating instructions. Use only
original Gerni spare parts.
Do not make any technical modi­fications to the high-pressure

cleaner.

Ensure that the machine is regu­larly serviced by authorized Gerni
dealers in accordance with the
maintenace plan. Failure to do
so will void the warranty.

CAUTION!
High-pressure hoses, fi ttings
and couplings are important
for the safety of the cleaner.
Use only high-pressure parts
approved by the manufac­turer!

The power cord must not differ
from the version specifi ed by the
manufacturer and may only be
changed by an electrician.
Please contact your local author­ized Gerni equipment distributor
for all other maintenance or re­pair needs!

Testing

The cleaner conforms to the Ger­man „Guidelines for Liquid Spray
Jet Devices“. The high-pressure
cleaner must be subjected to a
safety examination in accord­ance with the „Accident Preven­tion Regulations for Working
with Liquid Spray Jet Devices“
as required, but at least every
12 months, by an authorised
inspector.

After all repairs or modifica­tions to electrical equipment,
the protective conductor resist-

ance, the insulation resistance
and the leakage current must
be measured. Furthermore, a
visual inspection of the mains
power cord, a voltage and current
measurement and a function test
must be carried out. Our after­sales service technicians are
at your disposal as authorised
inspectors.

The complete „Accident Preven­tion Regulations for Working
with Liquid Spray Jet Devices“
are available from the Carl Hey­manns Verlag KG, Luxemburger
Strasse 449, 50939 Cologne or
from the appropriate associa­tion of employers’ liability insur­ances.

The pressure-bearing parts of
this high-pressure cleaner have
been manufactured in accord­ance with § 9 of the German
Pressure Vessels Ordinance
and successfully subjected to a
pressure test.

Bypass valve

The pressure is reduced by
means of a "bypass valve" which
returns water to the inlet side of
the pump at a minimum pressure.
The point at which this occurs is
set and sealed at the factory and
must not be adjusted.

2 Description

2.1 Purpose

This high-pressure cleaner has
been designed for professional
use. It can be used for cleaning
agricultural and construction

3.1 Setting up the cleaner

Every fuel-burning appliance,
such as pressure washers, de­pends upon a proper mix of fuel
and air (by

weight) for proper
combustion. Therefore some
adjustment of the air regulation
to the burner may be necessary
to take account of altitude and
the resulting air pressure. This
is true whether your fuel is ‘Nat­ural gas’, Propane or Diesel.
Your Gerni hot water pressure
washer was thoroughly tested
and adjusted for optimum per-

formance before it left our fac­tory. The factory is located at ap­proximately 120m (390 ft) above
sea level, and the combustion
settings are optimal for that el­evation.

If your location is higher than
1200m (3900 ft) above sea
level, your burner may require
re-adjustment for proper per­formance and best fuel econ­omy. Contact your Dealer or
Gerni for assistance.

3.2 Set the brake

1. Before using the cleaner for
the first time, check it care­fully to detect any faults or
damage.

2. Run the machine only when

it is in perfect condition.

3. Set the brake.

4. The slope of which the high

pressure cleaner is placed
must not exceed more than

10° in any direction.

into the fuel tank.
Bio-Diesel can be used, see
notes in chapter 1).
The fuel must be free from con­tamination.
Tank capacity see chapter 9.4
Technical data.

NOTE!

At temperatures below 8° C, the fuel
oil begins to solidify (paraffin precip­itation). This can lead to difficulties
in starting the burner. Before the
winter period either add a solidifica­tion point / flow improver (available
from the fuel oil trade) to the fuel or
use winter diesel fuel.

3.9 Connecting the high
pressure hose

3.9.1 Machines with high
pressure hose reel

1. Put the quick connector of
the high pressure hose onto
the nipple on the axle.

3.9.2 Machines without high
pressure hose reel

1. Put the quick connector of
the high pressure hose onto

3.7 Antiscale

The Nilfisk Alto Antiscale dosing
system is set by the factory.
To adjust the water hardness we
recommend that the inlet water
is tested accordingly.

Use the schematic to find the
right dosage of No Scale/anti
stone and water, and add the
mixture to the antiscale tank.

Machine flow L/h Pump size ml/h ˚dH ˚f ˚e Dosage

5 Applications and methods

Effi cient high pressure cleaning is achieved by following a few guide­lines, combined with your own personal experience of specifi c clean­ing tasks. Accessories and detergents, when correctly chosen, can
increase the effi ciency of your pressure washer. Here is some basic
information about cleaning.

5.1 Techniques

4.5 Using cleaning agents

1. Set the desired concentra­tion of cleansing agent at the
cleansing agent dosing facil­ity.

2. Spray the object to be cleaned.

3. Allow the cleaning agent to
work, depending on the de­gree of soiling. Then rinse off
with the high pressure spray
jet.

CAUTION!

4.4 Pressure regulation



For safety reasons,
never tie back or
wedge open the
trigger of the spray
gun in open

position during
operation. The trigger must be free
to close when released, thus

interrupting the fl ow of the water.

Options / model variants

Original instructions

5.1.1 Soaking

Encrusted or thick layers of dirt can be loosened or softened up by a
period of soaking. This is for example an ideal method within agricul­ture – for example, within pig sties. The ideal soaking method can be
achieved via use of foam or simple alkaline detergent. Let the product
lie on the dirty surfaces for around 30 minutes before pressure wash­ing. The result will be a much quicker high pressure cleaning process.

5.1.2 Detergent and Foam

Foam or detergent should be applied onto dry surfaces so that the
chemical product is in direct contact with the dirt. Detergents are
applied from bottom to top, for example on a car bodywork, in order
to avoid “super clean” areas, where the detergent collects in higher
concentration and streams downwards. Let the detergent work for
several minutes before rinsing before rinsing but never let it dry on
the surface being cleaned.

5.1.3 Temperature

Detergents are more effective at higher temperatures. Greases, oils
and fats can be broken down more easily at higher temperatures
also. Proteins can be cleaned at temperatures of around 60°C. Oils,
traffi c fi lm around 70°C, and grease can be cleaned at 80°C - 90° C.

5.1.4 Mechanical Effect

In order to break down tough layers of dirt, additional mechanical
effect may be required. Special lances and rotary or wash brushes
offer this supplementary effect that cuts through dirt.

5.1.5 High Water Flow or
High Pressure

High pressure is not always the best solution and high pressure
may damage surfaces. The cleaning effect also depends upon water
fl ow. Pressure levels of around 100 bar may be suffi cient for vehicle
cleaning (in association with hot water). Higher fl ow levels give the
possibility to rinse and fl ush away large amounts of dirt easily.

of insects etc, then rinse at low pressure and apply
normal car cleaning detergent. Let detergents settle
for 5 minutes before cleaning off. Metallic surfaces can
be cleaned using RimTop.

2. Proceed with cleaning using the high pressure lance.
Clean again from bottom to top. Use accessories to
clean in diffi cult to reach places. Use brushes in order
to add a mechanical cleaning effect. Short lances can
help for cleaning of motors and wheel arches. Curved
lances or undercarriage washers can be valuable for
the cleaning of car underchassis and wheel arches.

3. Clean fragile areas such as motors, rubber at lower
pressure levels to avoid damage.

4. Apply a liquid wax using the pressure washer in order
to protect the bodywork from pollution.

1. Apply thick foam over the surfaces to be cleaned. Apply
on dry surfaces. Apply from top to bottom on vertical
surfaces. Let the foam act for up to 30 minutes for the
optimal effect.

2. Proceed with cleaning using the high pressure lance.
Use applicable accessories. Use high pressure to
dislodge large amounts of incrusted dirt or grime.
Use lower pressure and high water volume in order
to rapidly fl ush away loose dirt and rinse surfaces.

3. Apply DES 3000 disinfectant once the surfaces are
perfectly clean.

Areas covered by amounts of loose dirt, such as animal
remains in slaughterhouses, can be removed by using
high water fl ow to fl ush away the dirt to evacuation pits
or drains.
Tank cleaning heads can be used to clean barrels, vats,
mixing tanks etc. Cleaning heads may be hydraulically or
electrically powered and give the possibility for automatic
cleaning without a constant user.

Rusted or dam­ages surfaces prior
to treatment

Wet Sandblasting
equipment

1. Connect the sandblasting lance to the pressure
washer and place the suction tube in the sand.

2. Always wear protective equipment during sandblast­ing.

3. Spray the surfaces to be treated with the mix of water
and sand. Rust, paint etc will be stripped off.
